FEATURES
These Attwood Stainless Steel Vertical Sidelights provide 2 Nautical
Mile visibility and are designed for boats up to 20 meters/65.6 feet.
The housing is corrosion-proof and the base gasket forms a seal
between the lens and deck for easy, water-resistant installation.
Lights meet USCG CFR 183.810, ABYC A-16 requirements, and all
applicable standards as tested by Immana Labs, 7/28/2003. Lights
use 8-watt festoon lamp, Attwood Part No. #9230 (13-volt) or #910409
(24-volt). See chart above for voltage.
REQUIRED FOR INSTALLATION
• Phillips screwdriver
• Cordless drill; 7/64" (#32 drill) and 3/8" (3 and 10mm) bits
• Three #6 pan head stainless steel tapping screws (not included)
• Marine-grade non-silicone sealant
• 16-gauge wire and waterproof crimp connectors
INSTALLATION LOCATION
Before drilling mounting holes, position sidelights on a surface
of the gunwale or deck where you are certain that sidelights:
• Are equal distance from the bow (Figure 1)
• Shine straight ahead
• Shine within 5° of horizontal when the boat is floating
• The light beam is not obstructed
Place lights with the red lens on the port (left) and green lens on
the starboard (right). Be sure there are no obstructions at the front
or side within the light’s arc of visibility (112.5 degrees each side).
INSTALLATION
1. To access light base mounting holes, remove exterior screw and
stainless steel or plastic lens helmet. (Figure 2)
2. Remove lens screw and colored lens. Save screws, helmet, and
lens for reinstallation.
3. Place light in position as shown in Figure 1.
4. Hold base with “FRONT” arrow pointing forward.
Important: Before drilling, be sure that light will shine straight ahead
and within 5° of horizontal when boat is floating.
5. Use base as a template to mark location of three mounting holes
and a center hole for wire access.
CAUTION
Position wire access hole carefully, especially on aluminum boats,
so that wires do not contact the hull.
6. Drill 3/8" (10mm) diameter hole for wire access and three 7/64"
(3mm) diameter holes for mounting screws. (Figure 2).
7. Bring one 16-gauge (+) and one (-) wire up through access hole.
DO NOT connect these wires to power until you read FINAL
WIRING INSTRUCTIONS (Figure 3)
8. Connect wires using waterproof crimp connectors.
9. Fasten light to deck with three #6 stainless steel screws. DO NOT
OVERTIGHTEN screws.
10. Replace lens over base. Replace lens screw.
11. Replace helmet over lens. Replace helmet screw.
FINAL WIRING INSTRUCTIONS
Use ONLY the rated voltage (see chart above). All positive wires
must be protected by a 1-amp fuse. Higher voltage or failure to make
proper wire and fuse connections will void the product warranty. Use
crimp type marine-grade connectors with suitable insulation. Protect
all connections with suitable materials.

1. Neatly thread wires to the switch, avoiding areas where abrasion
or snagging may occur.

ON/OFF/ON operation — one for running lights, and one for anchor
lights. Attach wires with crimp-on butt joint connectors. Test lights
for proper operation.
MAINTENANCE
To replace lamp: Remove the helmet and lens (Figure 2). Use small
slotted screwdriver to pry old lamp out of terminals. Replace with the
proper festoon-base lamp: Attwood #9230 (12-volt), or #910409
(24-volt). Replace lens, helmet, and retaining screws.
